Actually I would love to see Sugar coming back. I think Heroes VS Villians was a bad experience for her. But she single handedly owned Gabon and the entire season. Seriously and honestly, Gabon had one of the most amazing and memorable characters and tribal councils thanks to her.

i think that Christa from Pearl Islands should come back because she didn't do anything wrong and Sandra just blamed her for everything and she needs redemption because she made some stupid mistakes in the Pearl Islands like befriending Sandra and irritating people on her last day

They honestly have to go to Tonga for season 24 and do something new. Something like Big Brother, where 18 people 9 couples (and they know each other but they don't know that everyone has a partner BB6).
